摘要:
To obtain low insertion loss and low TTE level, a first central transducer, a second transducer and a third transducer are disposed on one surface of a piezoelectric substrate in such a manner that the second and the third transducers are in the direction of propagation (X-direction) of surface acoustic waves launched by the first transducer and the distance between center lines of the first and the second transducers and also the distance between the center lines of the first and the third transducers vary along the Y-direction perpendicular to the X-direction.

The copper or its alloys can be bonded to each other or can be bonded to noble metals or to other metals whose surface is covered with a noble metal thin film in an oxidative atmosphere. The surface of the copper or its alloys to be bonded should be covered with the layer of a noble metal thin film or a metal oxide remover or a conductive paste mainly consisting of a copper or copper alloy particles and the metal oxide remover. This method can be applied to a metallurgical industry and also to an electronics industry. This method is especially suitable for the production of a multilayered printed wiring board.

The present invention relates to a diffusion joining method of Cu or Cu alloy surface and a conductive paste used therefor, especially applied to a method for preparing a multilayer printed wiring board. The present invention is characterized by providing the contacting surfaces with a layer selected from the group comprising a noble metal thin layer, a metal oxide remover layer and a conductive paste layer mainly consisting of a Cu or Cu alloy particles and the metal oxide remover; and pressing the contacting metal surfaces at a temperature higher than 170.degree. C. more or less whereat the Cu atom at interface of the Cu or Cu alloy surfaces to be joined becomes to be able to diffuse, to give a joined metal body.
摘要:
A method of producing a substrate structure for a large size display panel. The method involves conveying a transparent substrate from a transparent substrate storage means in a conveying path through a vacuum chamber, and while conveying the substrate, forming at least a patterned transparent conductive film on a surface of the substrate by depositing strips of conductive film on the substrate through a pattern containing member extending in a direction orthogonal to the substrate conveying direction and having strip forming openings therein at intervals along the lengths thereof, and storing the transparent substrates with the strips thereon at the end of the conveying path.
